Stephon Marbury's recent Web show "is living proof" that the professional basketball player "has too much time on his hands," said Matt Murai in American Superstar Magazine. Since Friday, the NBA free agent has been streaming live video of himself from his home in Los Angeles. Among the "highlights": Marbury swallowing Vaseline to "soothe his sore throat" (watch) and a "nearly six-minute-long crying session as he listened to Kirk Franklin's 'Lean on Me.'" (watch) What's going on?

"Stephon Marbury has gone off the deep end," said Evans Clinchy in NESN.com. He's "reached the celebrity point of no return," where "he's so far removed from human civilization that nothing is surprising anymore," and it's "sad." He's also "on the sharp decline as a basketball player, and he's trying to move on to the next chapter in his life." This is a "way to make headlines, basketball talent or not—and look, it's working."

But "for some professional athletes," said Shannon J. Owens in the Orlando Sentinel, "today's media landscape is an ideal playground" where "they can self-promote, market, and directly communicate messages to their fan bases like never before." But clearly for others, "it's like putting a tub of ice cream in front of a 4-year-old—they don't know when to stop." The "smart" ones realize that a professional athlete's career is usually short, so they "look beyond the 15 seconds of fame and fortune and make plans for the next life transition."
